All times ET. 5:52 a.m.: Redburn Atlantic upgrades Shopify Redburn Atlantic thinks explosive growth in social e-commerce, where online shopping and social media platforms merge and allow companies to capitalize on impulse buying, can help expand Shopify's already strong position in the industry. The firm upgraded the e-commerce stock to buy from neutral. Its $99 price target implies more than 34% upside from Monday's close. "Shopify's industry-leading innovation, social media integrations, user-friendly platform and unique Shop Pay button functionality make it best positioned to capitalise on this structural growth," analyst Dominic Ball wrote. "Moreover, Shopify's ability to continue to win market share is backed by its extensive ecosystem and platform capabilities, which has cemented it as the ecommerce provider of choice for any merchant size." The analyst forecasts that social e-commerce can grow to $354 billion by 2028, which equates to a 42% compounded annual growth rate (CAGR) from $62 billion in 2023. Ball said this outlook is based on the U.S. social e-commerce market following in the trajectory of the segment's growth seen in China. "Shopify holds a significant advantage in the social ecommerce space, with its breadth of direct social media integrations that are crucial for social ecommerce," Ball added. "A standout example is YouTube, where Shopify remains the sole ecommerce platform with direct integrations." Shopify has ticked down roughly 6% in 2024.

Analyst Christopher Danely lowered his price target on the chipmaker to $150 from $175. To be sure, he maintained his buy rating, and the new forecast still implies upside of 72% from Monday's close. Micron is set to release fiscal fourth-quarter results on Sept. 25. "We expect the company to post results and guidance below Consensus driven by legacy DRAM weakness," Danely said in a note. "While it appears there has been an inventory build in DRAM in the PC and handset end markets, we believe this should finish by the end of the year." "More importantly, we expect Micron's revenue and gross margins to increase for the next several quarters," he added. Micron shares are up just 2% this year.
